Question

David Huxley holds the record for the heaviest plane pulled. He pulled 184 tons, 91 m in 1 min and 27 seconds. What is his average mph?

Answer 1

Average speed in m/s:

$V=S/t = 91m/87s = 1.046m/s$

$1miles/hour = 1609m/3600s = 0.447m/s$

Average speed in mph:

$V=\frac{1.046m/s}{0.447m/s}=2.32miles/hour$
